MT3608 Boost Converter

The MT3608 Boost Converter is a compact DC-DC step-up module that converts low input voltages to higher output voltages up to 28V. It is ideal for powering higher-voltage devices from single-cell LiPo, USB, or other low-voltage sources.

Key Features

• Step-up conversion from 2V-24V input
• Adjustable output up to 28V
• 2A max switch current
• High efficiency up to 93%
• Compact design with potentiometer adjustment
• Built-in overcurrent protection
• Low cost boost solution

Technical Specifications

Applications

• Power 12V devices from 5V USB
• LiPo battery boost to higher voltages
• LED strip power from low voltage
• Single-cell battery projects
• Portable electronics requiring voltage step-up
• Nixie tube power supply (higher voltage)

Important Notes

• Adjust output voltage BEFORE connecting load
• Input current must not exceed source capability
• Efficiency decreases as voltage step-up ratio increases
• Heat generation increases with load – add heatsink for high current
• Maximum output current depends on input/output voltage ratio
• Do not exceed 28V output or 2A switch current
